Slick bolt! July 30, 2025 : Scott C from Suwanee, GA United States   Owned many AR platforms and had a few fancy bolts, but this is clearly high quality.  I would say it feels slippery.  I added a tiny amount of Slip EWL 2000 and its functioning great.  Cleaning carbon is a breeze.  It included an O-ring under the extrator so it grabs and removes brass with ease.  Always a great experience ordering from MAS.  Buy with confidence.

Awesome quality March 27, 2025 : Justin Peters from Stafford, VA United States   Mas Defense produce some of the best nickel boron BCGs. I have a AR10 AND AR15 BCG from Mass Defense. With their quality in their BCGs, I could only imagine and wish for them to produce barrels, uppers and lowers. Customer service is awesome and shipping is packaged great and fast. Can't beat the price for their quality. Thanks Mas Defense. Was this review helpful to you?
